I have just installed Moodle 3.8.3 and when I looked at the security report, the Default role for all users has a critical error -  The default user role "Authenticated user" is incorrectly defined!

I followed the posted solution to reset the authenticated user role to its default permissions but that dis not solve the problem.  I then saw this post - https://moodle.org/mod/forum/discuss.php?d=403379#p1628062 which suggested the problem is that the permission -  tool/dataprivacy:requestdelete" with risk RISK_DATALOSS is allowed by default for this role.  When I changed the setting on this role to Prevent, the critical error went away.  But it does seem like you would want users to be able to request delete, which is why this seems like a bug.
